Recording apparatus and method of calculating density in vicinity of the same

A recording apparatus includes: a receiver receiving recording data transmitted from a user; a recording section performing recording on a medium using the recording data; a storage section temporarily storing the recording data until the recording is finished; an output tray to which the medium with the recording finished is outputted; and a controller controlling the recording apparatus. Here, when an index indicating the size of a value of the number of users predicted to congregate near the recording apparatus is a density near the recording apparatus, the controller calculates the density based on information concerning recording data stored in the storage section, and enables the density to be referred to.
